    摘要: An electromagnetic bearing apparatus having five degrees of freedom includes two radial magnetic bearings. Each of the radial bearings consists of two pairs of electromagnets. The electromagnets of one pair are arranged opposite one another around a rotating shaft, and the other pair is arranged in the same perpendicular plane as the preceding pair. The pairs of electromagnets in the two radial bearings are respectively controlled to stabilize the rotating shaft to obtain automatic regulation, in which deviation of the shaft in a radial sense is compensated according to the component of shaft radial deviation and deviating velocity and the gyro-effect which will be caused by the perpendicular compensating torque to compensate the future rotation in the perpendicular component.

    摘要: Monodisperse colored spherical particles each having two separated color regions of two hues, that is, two-colored spherical particles, useful, for example, for displays of characters, graphics, images and the like, the two hues being for reverse display in terms of electricity and magnetism from the viewpoint of good suitability for display are provided. In the production process and the apparatus for producing the colored spherical polymer particles, microchannels are utilized including a first microchannel through which a colored continuous phase comprising a color dye/pigment dispersed in a fluid dispersing medium containing a polymerizable resin component and having colored phases of different hues is transferred, and a second microchannel through which a spheroidizing disperse phase flows. The process and apparatus spheroidizes the discharged colored continuous phase having two hues and cures the polymerizable resin component in the colored continuous phase, whereby colored spherical polymer particles are formed.
